[Outline of the invention]

[Technical task]

Incidentally, an operating handle of a device such as a vehicle may generate vibrations due to transmission of vibrations of the device itself (vehicle body). To suppress these vibrations, the following technology is known to suppress handle vibrations. The technique is to attach a handle weight to one end of a handle, etc. to suppress the amplification of vibrations at the end of the handle.

However, mounting the above-described transducer and the handle weight together on a handle of a limited size creates the following problems. That is, it is difficult to ensure space for placing the parts, and the cost of the parts also increases.

The purpose of the present invention is to provide an operating handle structure for a device which can efficiently convey information to a user grasping a handle and suppress vibrations of the handle.

[solution to the task]

As a solution to the above object, one aspect of the present invention is an operating handle structure of a device comprising: a handle (41A, 51A) capable of operating a device (1) and being grasped by an operator ; and a vibration device (46, 56) which transmits vibrations to the handle (41A, 51A) and informs the operator of information, the vibration device (46, 56) being on a side of an end portion (37a) of the handle (41A, 51A). is arranged.

According to this configuration, the vibration device that informs the operator of information can be used as a handle weight to suppress the vibrations of the handle. Therefore, there is no need to provide a handle weight separately from the vibration device. Therefore, the increase in a space in which the handle and parts are arranged around the handle and the increase in cost of parts can be suppressed. Therefore, it is possible to efficiently convey information to the operator who grips the handle and suppress the vibration of the handle. The above “side of the end part” includes a perimeter of the end part, such as an outside and an inside of the end part.

In the above aspect, the vibration device (46, 56) may be provided with an actuator (71) and an eccentric weight (72), and is disposed in a hollow portion (37c) within the handle (41A, 51A).

According to this configuration, since the vibration device including the actuator and the eccentric weight is used as the handle weight, there is no need to provide a handle weight separately from the vibration device. Therefore, the increase in a space in which the handle and parts are arranged around the handle and the increase in cost of parts can be suppressed. Therefore, it is possible to efficiently convey information to the operator gripping the handle and suppress the vibrations of the handle.

In the above aspect, a rotation axis (71a) of the actuator (71) may be arranged parallel to a center axis line (83) of the handle (41A, 51A).

According to this configuration, the actuator and the eccentric weight connected to the rotation axis of the actuator can be easily accommodated in the hollow portion within the handle.

In the above aspect, a support portion (81d1, 81b1) which supports the actuator (71) in the handle (41A, 51A) on a side where the operator is placed can be separated from the center axis line (83) of the handle (41A, 51A). 41A, 51A) carries, also be included.

According to this configuration, the vibrations of the vibrating device are more easily transmitted to the hand gripping the handle by providing the supporting portion of the actuator on the operator's side of the handle. Therefore, the sharing of information to the operator can be performed better.

In the above aspect, the handle (41A, 51A) may be provided with a left-and-right pair of handles (41A, 51A) to be gripped by a left and right hand of the operator, respectively, and the eccentric weight ( 72) may be disposed on an inner side of the handle (41A, 51A) in a left-right direction of the actuator (71).

According to this configuration, since the eccentric weight is disposed on the inner side (base end side) of the handle in the left-right direction, the transmission of information to the operator can be better performed. That is, the vibrations caused by the rotation of the eccentric weight can be more easily transmitted to the hand gripping the handle than when the eccentric weight is disposed on the outside (tip end side) of the handle in the left-right direction .

In the above aspect, a wire harness (76) disposed within the handle (41A, 51A) and connected to the actuator (71) may further be included.

According to this configuration, since the wire harness connected to the actuator is disposed within the handle, disturbances such as water ingress to the wire harness can be suppressed. Additionally, the wiring harness can be made inconspicuous to improve its appearance.

[Advantageous Effects of the Invention]

According to the present invention, it is possible to provide an operating handle structure for an apparatus which can efficiently convey information to the operator grasping the handle and suppress vibrations of the handle.

The motorcycle 1 has a front wheel 3, which is controlled by a handlebar (operating handle) 2, and a rear wheel 4, which is driven by a power unit 20. The motorcycle 1 is a semi-trailer vehicle in which a rider sits astride a vehicle body. The motorcycle 1 can tilt (tilt) its body in the left-right direction (rolling direction) with respect to the ground contact points of the front and rear wheels 3, 4. The vehicle of the embodiment is a vehicle that rotates in the direction in which the vehicle body is tilted, such as, but not limited to, the motorcycle. The vehicle of the embodiment may include a vehicle that rotates by steering the handlebars without tilting the vehicle body.

The motorcycle 1 is provided with steering system parts 10A including the handlebar 2 and the front wheel 3, and a vehicle body frame 5 functioning as a frame member of the motorcycle 1 is used. The steering system parts 10A are supported by a head pipe 6 at the front end portion of the vehicle body frame 5 so as to be steered. The front wheel 3 is supported by the lower ends of a left and right pair of front forks 10 in the steering system parts 10A.

The front wheel brake 3B and the rear wheel brake 4B brake the rotation of the front wheel 3 and the rear wheel 4 appropriately. This braking is carried out by operating a brake lever 43 (see 2 ) and a brake pedal (not shown), which are brake actuating elements.

2 shows an area around the handlebars 2 on the front portion of the vehicle body, viewed from the driver's perspective. The upper portions of the left and right front forks 10 are supported by the head pipe 6 by means of a handlebar stub 31. The left and right front forks 10 are telescopic buffers. The handlebar stub 31 has an upper bridge 32 and a lower bridge 33 and a stub shaft 34. The upper bridge 32 and the lower bridge 33 connect the upper portions of the left and right front forks 10. The stub shaft 34 is inserted into the head pipe 6. The front portion of the vehicle body is covered by the front hood 27 of the vehicle body cover 12.

For example, the handlebar 2 of the motorcycle 1 is a separate left and right handle. The handlebar 2 has a left and right pair of a right handle 36 and a left handle 37. For example, the right handle 36 and the left handle 37 are each attached to the upper portion of the front fork 10 on the same side below an upper bridge 32.

The right handle 36 is provided with a right handle 41A, which the driver grips with his right hand. The right handle 41A includes a cylindrical right handlebar 36A extending in a straight line with a length in the vehicle width direction, and a throttle sleeve 41 externally fitted to the right handlebar 36A in a manner rotatable about its axis . The right handle bar 36A is constructed of a metal tube or the like. The throttle sleeve 41 is constructed of a rubber grip fixedly attached to a periphery of a resin main body.

The right handlebar 36A extends inwardly from the throttle sleeve 41 in the vehicle width direction. A right switch box 42 and a right lever holder 44 are on the inner side of the right handle bar 36A in the vehicle Worn in the width direction. A reference numeral 43 in the figure denotes a right handle lever (eg, a front brake lever) which is pivotally supported by the right lever holder 44. An inner end portion of the right handle bar 36A in the vehicle width direction is secured to the upper portion of the right front fork 10 by means of a right handle clamp member 36B.

The right handle 41A is provided with a right vibration device 46 in an inner space (hollow portion) of the right handle bar 36A. The right vibration device 46 is used to provide vibrations to the driver's right hand for information transmission.

The left handle 37 is provided with a left handle 51A which the driver grasps with his left hand. The left handle 51A includes a cylindrical left handlebar 37A extending in a straight line with a length in the vehicle width direction, and a handle grip member 51 fixedly attached to the left handlebar 37A. The left handle bar 37A is made of a metal tube or the like. The handle grip member 51 is a synthetic rubber grip.

The left handle bar 37A extends inwardly from the handle grip member 51 in the vehicle width direction. A left switch box 52 and a left lever holder 54 are supported on the inner side of the left handlebar 37A in the vehicle width direction. A reference numeral 53 in the figure denotes a left lever (e.g., a clutch lever). An inner end portion of the left handle bar 37A in the vehicle width direction is secured to the top of the left front fork 10 by means of a left handle clamp member 37B.

The left handle 51A is provided with a left vibration device 56 in an inner space (hollow portion) of the left handle bar 37A. The left vibration device 56 is used to provide vibrations to the driver's left hand for relaying information.

An instrument device 61 is arranged in front of the front fork 10. The instrument device 61 is supported by the vehicle body frame 5 or the front hood 27. The instrument device 61 is provided with a display screen 62 and a display lamp group 63. The instrument device 61 is configured, for example, by a liquid crystal display that displays images of a vehicle speed and an engine speed. The display lamp group 63 is arranged around the display screen 62 to notify the driver of various information.

The display lamp group 63 is provided with a right display lamp 66 disposed on a right side of the display screen 62 and a left display lamp 67 disposed on a left side of the display screen 62. The right indicator lamp 66 emits light associated with activation of the right vibration device 46. The left indicator lamp 67 emits light in connection with activation of the left vibration device 56. The display screen 62 notifies the driver of predetermined information by displaying predetermined images. The indicator lamp group 63 notifies the driver of predetermined information by making a predetermined light display (light or flash). The predetermined information includes, for example, various notifications and warnings such as those related to operation support control and automatic operation control of the motorcycle 1. The notification of the indicator lamp group 63 is carried out in cooperation with the left and right vibration devices 46, 56.

Incidentally, a semi-riding vehicle such as the motorcycle 1 has specific vibration, such as vibration of the engine and other driving power, vibration caused by uneven road surfaces, vibration caused by tire irregularities, and the like. Therefore, vibrations using a general vibration element may be lost in the aforementioned specific vibrations, and the driver may not perceive the warning.

The left and right vibration devices 46, 56 generate predetermined vibrations to notify and warn the driver. The left and right vibration devices 46, 56 produce vibrations as the aforementioned notification and warning in a frequency band that avoids vibration frequencies specific to the semi-riding vehicle such as the motorcycle 1.

This makes it difficult to merge the vibrations as notifications and warnings with the wheel vibrations and engine vibrations, etc., which are specific to the semi-trailer vehicle. This makes it possible to provide good notification of information that is easily perceived by the driver. The vibrations as notifications and warnings are so-called haptic vibrations. This vibration stimulates the tactile sense of the driver's hands gripping the left and right handles 41A, 51A.

3 is a perspective view transparently showing an interior of the left handle 37. The vibration device 56 arranged within the left handle 37 is described below. In 3 is on the handle grip element 51 (see 2 ) of the left handle 37 is omitted. A detailed description of the right vibration device 46 accommodated within the right handle 36 is omitted since it has the same structure as the left vibration device 56 (the same applies to 4 and 5 ).

The left vibration device 56 has an electric motor (actuator) 71 and an eccentric weight 72. The electric motor 71 is supported (attached) to an inner peripheral surface 37d of the hollow portion 37c of the left handle bar 37A. The eccentric weight 72 is integrally rotatable and supported on a tip end portion of a rotation axis 71a of the electric motor 71. A cap 73 is attached to an outer end portion 37e of the left handle bar 37a in the left-right direction to seal the hollow portion 37c. The entire left vibration device 56 is disposed inside in the left-right direction from a distal end of the end portion 37e of the left handle bar 37A. At least a part of the left vibration device 56 may be disposed outside in the left-right direction from the distal end of the end portion 37e of the left handle bar 37A. In this case, the left vibration device 56 may be configured to be covered with a suitable cap.

In the electric motor 71, driving, stopping, and rotation speed of the rotation axis 71a are controlled. This control is performed by a control device (not shown) provided in the vehicle body based on various information. The electric motor 71 has a cylindrical housing 75 which covers an outer circumference around the rotation axis 71a.

For example, a wire harness 76 extends from an outer peripheral surface 75a of the housing 75. The wire harness 76 has a plurality of conductors (not shown). The wire harness 76 supplies control signals from a control device, not shown, and power from a battery, not shown, to the electric motor 71.

The wire harness 76 is arranged to extend in the left handlebar 37A from the electric motor 71 to the inner side in the vehicle width direction. The wire harness 76 is made from the left handle bar 37A near the left handle clamp 37B (see 2 ) is pulled out and connects to a main wiring harness, not shown.

For example, the eccentric weight 72 is formed in the shape of a shortened half-cylinder. The eccentric weight 72 is aligned with the rotation axis 71a of the electric motor 71 in the axial direction. The eccentric weight 72 is provided with a flat surface portion 72a along the axial direction and a shaft mounting portion 72b aligned with the rotation axis 71a. The center of gravity of the eccentric weight 72 is eccentric with respect to the rotation axis 71a. The eccentric weight 72 rotates with the rotation axis 71a by operating the electric motor 71 to generate vibrations in the left vibration device 56. Consequently, the left handle bar 37A on which the left vibration device 56 is mounted vibrates, and the vibrations are transmitted to the left hand of the driver holding the handle grip member 51. These vibrations notify the driver of predetermined information.

By installing the weighted electric motor 71 and the eccentric weight 72 inside the hollow left handlebar 37A, the following effect is achieved. That is, the left vibration device 56 can be used as a handle weight to suppress vibration generation due to resonance of the left handle 37. Therefore, there is no need to install a separate handle weight on the left handle 37 and there is no need to add space for placement of parts within and around the left handle 37. In addition, the increase in the number of parts and the assembly structure can be suppressed, and a reduction in costs can be ensured.

The eccentric weight 72, which is the source of vibrations of the left vibrator 56, is disposed on an inner side of the left handle 37 in the left-right direction. The inner side of the left hand grip 37 in the left-right direction is a thumb side of the driver's hand. The thumb side of the driver's hand is a side on which the driver's hand tends to be in constant contact therewith even when the fingers operating the lever in front of the left hand grip 37 are disengaged from the left hand grip 37. Therefore, by arranging the eccentric weight 72 on the inner side of the left handle 37 in the left-right direction Vibrations transmitted more easily to the driver's hand.

For example, the weight of the electric motor 71 is heavier than that of the eccentric weight 72. The electric motor 71 is disposed on an outer side of the eccentric weight 72 in the vehicle width direction. By arranging the weighted electric motor 71 on an outer side of the left handle 37 in the left-right direction (a distal end side), the following effect is achieved. That is, the left vibration device 56 can simply act as a handle weight, and the effect of suppressing vibrations of the left handle 37 is enhanced.

As in 4 As shown, the electric motor 71 is supported (attached) to the inner peripheral surface 37d of the left handlebar 37A by means of a spacer 81.

For example, the spacer 81 has a cylindrical shape coaxial with the left handle bar 37A. The spacer element 81 has its outer peripheral surface 81a which is adapted to the inner peripheral surface 37d of the left handle bar 37A. The spacer 81 includes a cylindrical peripheral wall 81b constituting the outer peripheral surface 81a, and a plurality of inwardly projecting portions 81d protruding inward in a radial direction from the inner peripheral surface 81c of the peripheral wall 81b.

The plurality of inwardly projecting portions 81d hold the electric motor 71 by pressing an inner end surface 81e in the radial direction against the outer peripheral surface 75a of the housing 75 of the electric motor 71. In other words, the spacer 81 holds the electric motor 71 by fitting the electric motor 71 within each inner end surface 81e. A space S1 extending along the axial direction of the left handle bar 37A is provided between the circumferentially adjacent inwardly projecting portions 81D. This space S1 promotes heat dissipation from the electric motor 71.

Between the left handlebar 37A and the spacer 81 there is a baffle (not shown) which prevents relative rotation in the circumferential direction. The same baffle is also provided between the spacer 81 and the housing 75.

A reference numeral 83 in the figure denotes a center axis line (shaft center) passing through the center of the transverse portion of the left handle bar 37A, which extends in a straight line. A reference numeral 71b in the figure denotes the center axis line (shaft center) of the rotation axis 71a of the electric motor 71. In the embodiment, these two center axis lines 83, 71b coincide. That is, the electric motor 71 is arranged with the axial direction parallel to and coinciding with the left handle bar 37A.

At least one of the plurality of inwardly projecting portions 81d is disposed at the rear side of the vehicle (driver's side) from the center axis line 83. This inwardly projecting portion 81d on the rear side is designated by a reference numeral 81d1. The rear side of the left handle 37 is a side with which the driver's palm tends to be in constant contact regardless of whether the lever is operated or not. Therefore, by providing support for the electric motor 71 (inwardly projecting portion 81d1) on the rear side of the left handle 37, vibrations are more easily transmitted to the driver's hand.

The spacer 81 is made of resin or metal. When the left vibrator 56 serves as the handle weight, the material of the spacer 81 can be selected according to the required weight. In other words, when the left vibration device 56 alone is sufficient to provide the weight required as the handle weight, the spacer 81 may be made of resin. If the left vibrator 56 alone is not sufficient to provide the weight required as the handle weight, the spacer 81 may be made of metal. For example, when the weight of the handle weight is adjusted with the metal spacer 81, the thickness of the peripheral wall 81b and the cross-sectional area of the inwardly projecting portion 81d of the spacer 81 can be increased. When the spacer 81 is made of metal, good heat dissipation from the electric motor 71 is achieved by using the good thermal conductivity of metal.

5 shows an example in which the electric motor 71 is arranged eccentrically, in contrast to that in 4 embodiment shown.

In this example, both of the center axis lines 83, 71b of the left handle bar 37A and the electric motor 71 are parallel to each other. The center axis line 71b of the electric motor 71 is offset from the center axis line 83 of the left handle bar 37A to the rear side by a distance L1.

The electric motor 71 is supported (fixed) on the inner peripheral surface 37d of the left handle bar 37A by means of a spacer 85.

For example, the spacer 85 includes a cylindrical peripheral wall 81b forming an outer peripheral surface 81a, and a plurality of inwardly projecting portions 81d which protrude inwardly in a radial direction from an inner peripheral surface 81c of the peripheral wall 81b.

The spacer 85 has fewer inwardly projecting portions 81d than the spacer 81 of the embodiment. The spacer 85 does not support a rear portion of the outer peripheral surface 75a of the housing 75 of the electric motor 71 through the inwardly projecting portions 81d. The spacer 85 supports the rear portion of the outer peripheral surface 75a with a rear portion 81b1 of the peripheral wall 81b. The rear portion of the outer peripheral surface 75a of the housing 75 of the electric motor 71 is pressed against the inner peripheral surface 81c of the rear portion 81b1 of the peripheral wall 81b of the spacer 85. Consequently, the vibrations generated by the left vibration device 56 are directly transmitted to the driver's left hand.

Therefore, by eccentrically arranging the electric motor 71 rearward in the left handlebar 37A, the vibrations generated by the left vibration device 56 are more easily transmitted to the driver's palm.

As explained above, the operating handle structure of the device in the above embodiment is provided with the handlebar 2, which enables steering of the motorcycle 1. The handlebar 2 is provided with the right handle 41A and the left handle 51A gripped by the rider, and the right vibration device 46 and the left vibration device 56 located in the hollow portion 37c within each of the right handle 41A and the left handle 41A left handle 51A are arranged. The right vibration device 46 and the left vibration device 56 provide vibration as a predetermined information notification to the driver's hand gripping the right handle 41A and the left handle 51A. The right vibration device 46 and the left vibration device 56 are provided with the electric motor 71 and the eccentric weight 72, respectively. The right vibrator 46 and the left vibrator 56 serve as the handle weight, respectively. The handle weight suppresses vibrations in the frequency band specific to the motorcycle 1 in the right handle 41A and the left handle 51A.

According to this configuration, the right vibration device 46 and the left vibration device 56 provided with the electric motor 71 and the eccentric weight 72 are used as handle weights to suppress vibrations in the frequency band specific to the motorcycle 1, whereby eliminating the need to provide separate handle weights from the right vibrator 46 and the left vibrator 56. Therefore, the increase in a space in which the handle 2 and parts are arranged around the handle 2 as well as the increase in the cost of parts can be suppressed. In addition, it is possible to efficiently communicate information to the driver gripping the right handle 41A and the left handle 51A and suppress vibrations of the right handle 41A and the left handle 51A.

In addition, in the operating handle structure of the device described above, the right vibration device 46 and the left vibration device 56 are provided with the electric motor 71 and the eccentric weight 72 driven by the electric motor 71. This makes it possible to easily ensure the weight as the handle weight.

In addition, in the operating handle structure of the device described above, the rotation axis 71a of the electric motor 71 is arranged parallel and coaxial with the center axis line 83 of the right handle 41A and the left handle 51A. This makes it possible to easily accommodate the electric motor 71 and the eccentric weight 72 in the hollow portion 37c within the right handle 41A and the left handle 51A. In addition, the rotation radius of the eccentric weight 72 can be ensured to the maximum extent.

In addition, in the operation handle structure of the above device, the supporting portion (the inwardly projecting portion 81D1, the rear portion 81B1 of the peripheral wall 81B) is provided on the side (the rear side) where the driver is placed from the center axis line 83 in the right handle 41A and the left handle 51A. The supporting section supports the electric motor 71 on the right handle 41A and the left handle 51A.

According to this configuration, the supporting portion of the electric motor 71 is provided on the driver's side of the right handle 41A and the left handle 51A to provide good information notification to the driver. In other words, the vibrations of the right vibrator 46 and the left vibrator 56 can easily be transmitted to the hand which grips the right handle 41A and the left handle 51A.

In addition, in the operating handle structure of the device described above, the handlebar 2 configures the left and right pairs of handles 41A, 51A, which are gripped by the driver's left and right hands, respectively. The handles 41A, 51A are supported by the main body of the vehicle body at base end portions on the inner side in the vehicle left-right direction and extend outward from the base end portions in the left-right direction. The eccentric weights 72 are arranged on the inner side of the handles 41A, 51A in the left-right direction of the electric motor 71.

According to this configuration, since the eccentric weights 72 are arranged on the inner side (base end side) of the left and right handles 41A, 51A in the left-right direction, the information can be conveyed to the driver better than when the eccentric ones Weights 72 are arranged on the outer side (tip end side) of the left and right handles 41A, 51A. In other words, the vibrations caused by the rotation of the eccentric weights 72 can be easily transmitted to the hands gripping the left and right handles 41A, 51A.

In addition, in the operation handle structure of the above-described device, the wire harness 76 is provided, which is disposed within the handles 41A, 51A and connected to the electric motor 71. This makes it possible to suppress disturbances such as water entering the wire harness 76, etc., as well as to make the wire harness inconspicuous to improve its appearance.

The invention is not limited to the above embodiments. For example, the vibration device is not limited to those driven by an electric motor. For example, the vibration device may be equipped with an actuator that generates a driving force by pneumatic, hydraulic, magnetic means or the like, and a weight that is driven by the actuator to generate vibration.

The eccentric weight is not limited to the configuration in which the eccentric weight is disposed on the inner side in the left-right direction of the electric motor. For example, the eccentric weight may be disposed on the outer side in the left-right direction of the electric motor. In this case, the eccentric weight is driven at the end side of the handle, making it easier to generate vibrations as an information notification throughout the handle. It is also easier to adjust the weight of the eccentric weight to act as the handle weight.

The methods of attaching the spacer to the handle and attaching the electric motor to the spacer are not applicable to those described in 4 and 5 limited to the procedure described. For example, the spacer element can be attached to the handle by screwing and hammering. The electric motor can be attached to the spacer element by screwing and hammering.
